IMPROVED BRUSH-HEAD.

Toall lwhomnt may concern: f

Be it known that we, OYRUS G. Moons and Luvl S. GAMBOLD, both of Coatesville, in the county of'Hendricks, and.State of Indiana, have invented new and useful Improvements in Brush-Heads; and we do hereby declare that the lfhllowing is a full, clear, and exact description thereof, that will enable skilled artisans to make and-use-the same, reference .being had to the accompanying drawing, and to the letters of reference marked thereon, making part of this specification..

This invention relates to construction ofthe brushvhead, and consists in making itin two cone-shaped halves, to .receive the bristles, and arranging the hanv die to screw into the head, with a conical point to enter the centre of the bundle ofbristles, and wedge them securely against the sides of the shell, or socket, and 'thus hold them from coming out.

The construction is also such that the bristles may be readily renewed at pleasure.

in the half attached to the but-piece B, and then cov,- ered by the other half.

The two halves are secured together, by means of grooved dovetail-clamps O 0, that slide upon' corre- Figure 1 is,a vertical transverse' section through the sponding flanges D D, on the contiguous edges of the two halves ofthe socket.

When the bristles are clamped in the socket in this manner, they are wedged tight therein, by means of the conical point E, on the end ofthe screw F, which enters the centre ofthe bundle of bristles, as the handle G is screwed into the but-piece B.

Although the two halves of the socket are here represented as secured together by means of the dovetail clamps C C, they may besecured in any other suitable manner. One-half may be hinged to the other, and secured on the other side, by a similar clamp to O, or the two halves may be secured together by screws through flanges on their edges.

The advantage of constructing thehead in two halves is, that a bundle of bristles that will compactly fill the socket may be readily placed therein, and this, combined with the conical shape of the socket, and of the point E, driven into the centre of' the bundle of bristles, secures them from coming loose.

This construction of the brush-head also renders the renewal of the brush easily and conveniently executed.

Having thus fully described our invention 'What we claim as new, and desire to secure by Letters Patent, is

Constructing the brush-head in two cone-shaped halves, secured together by the clamps O O, and, in combination therewith, the cone-shaped point E, on the end of the screw F, all arranged to operate in the manner substantially as set forth.
